The electromagnet is positioned between your poles of another magnet. When current from the voltage supply flows through the coil, a magnetic field is created around the electromagnet. The poles of the 
magnet connect to the poles of the electromagnet, Electromagnetic Motor china leading to the motor to carefully turn. … The more coils, the stronger the motor.
When an electric current flows through a loop or coil of wire, placed between the two poles of an electromagnet, the electromagnet exerts a magnetic force on the wire and causes it to rotate. The rotation of the wire starts the engine. As the wire rotates, the electric energy changes directions.
